5. Select System > Services > DHCP Snooping > Interface Configuration.
6. Select one or more interfaces by taking one of the following actions:
• To configure a single interface, select the check box associated with the port, or type
the port number in the Go To Interface field and click the Go button.
• To configure multiple interfaces with the same settings, select the check box
associated with each interface.
• To configure all interfaces with the same settings, select the check box in the heading
row.
7. From the Trust Mode menu, select the desired trust mode:
• Disabled. The interface is considered to be untrusted and could potentially be used
to launch a network attack. DHCP server messages are checked against the bindings
database. On untrusted ports, DHCP snooping enforces the following security rules:
- DHCP packets from a DHCP server (DHCPOFFER, DHCPACK, DHCPNAK,
DHCPRELEASEQUERY) are dropped.
- DHCPRELEASE and DHCPDECLINE messages are dropped if the MAC address
is in the snooping database but the binding’s interface is other than the interface
where the message was received.
- DHCP packets are dropped when the source MAC address does not match the
client hardware address if MAC address validation is globally enabled.
• Enabled. The interface is considered to be trusted and forwards DHCP server
messages without validation.
8. Click the Apply button.
The updated configuration is sent to the switch. Configuration changes take effect
immediately.
